Reading DTC Memory
The DTC memory can only be read with the HHT.
- Readout with impulse counter was eliminated.
- Standard communications correspond to SAE-Standard, ISO 9141 CARB.
- In compliance with legislative standards, the DTC's can be read with a generic scan tool at the diagnostic module (OBD II) generic scan tool connector (X11/22).

NOTE: The diagnostic trouble code read at X11/22, however, is different from that of the HHT. See DTC Tables in the "Diagnosis" section.
